From that diff it looks to me that if ~/.mozilla exists OR if MOZ_LEGACY_HOME is set it uses ~/.mozilla, otherwise it uses the $XDG_CONFIG_HOME/.mozilla directory instead.

So no migration to the XDG directory, but also no throwing away your existing data either.

That’s the safest.

Who knows what might be touching that data today. Or backing it up, etc

[gen2brain]

I know a few apps that did the same (mpv for example). If you still have it in home root it uses that, when you move it to .config it uses that instead. Auto migrating could and would create issues.

So is it safe to just manually move $HOME/.mozilla to $HOME/.config/mozilla ?

[aallaall]

That’s the hard part to answer, that Mozilla leaves to you!

[neilv]

I would guess not. I see `.mozilla` absolute pathnames within some files in a profile directory (specifically, `extensions.json` and `pkcs11.txt`).

(This has bitten me before. I don't know why it was done that way.)

[Gabrys1]

I think yes. And that's maybe the reason they didn't properly split the files to .cache/ .config etc
